2csc(x)+4=0

解答

2 csc (x) + 4 = 0

解答

x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

+1

度数

x = 21 0^{\circ} + 36 0^{\circ} n, x = 33 0^{\circ} + 36 0^{\circ} n

求解步骤

2 csc (x) + 4 = 0

将

4

到右边

2 csc (x) + 4 = 0

两边减去

4

2 csc (x) + 4 - 4 = 0 - 4

化简

2 csc (x) = - 4

2 csc (x) = - 4

两边除以

2

2 csc (x) = - 4

两边除以

2

\frac{2 csc ( x )}{2} = \frac{- 4}{2}

化简

\frac{2 csc ( x )}{2} = \frac{- 4}{2}

化简

\frac{2 csc ( x )}{2} : csc (x)

\frac{2 csc ( x )}{2}

数字相除:

\frac{2}{2} = 1

= csc (x)

化简

\frac{- 4}{2} : - 2

\frac{- 4}{2}

使用分式法则:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{4}{2}

数字相除:

\frac{4}{2} = 2

= - 2

csc (x) = - 2

csc (x) = - 2

csc (x) = - 2

csc (x) = - 2

2sin(x)=sqrt(3),0<= x<= 2pi

2 sin (x) = 3, 0 \leq x \leq 2 π

solvefor x,z=arcsin(x+y)

so l v e f or x, z = arcsin (x + y)

8sin^2(x)-6sin(x)+1=0

8 sin^{2} (x) - 6 sin (x) + 1 = 0

2cos^2(t)+2cos(2t)=0

2 cos^{2} (t) + 2 cos (2 t) = 0

arcsin(2x)+arcsin(x)=(2pi)/3

arcsin (2 x) + arcsin (x) = \frac{2 π}{3}
